| Research Abstract |
We developed a new MRI system for diagnosing seminiferous tubule morphology. The system consists of a highly sensitive radiofrequency coil for receiving MR signal from the testis and software for classifying seminiferous tubule MRIs based on 16 morphological features. We succeeded in the visualization of animals' seminiferous tubules (approximately 200 μm in diameter) on high-resolution MRIs, and the software enabled to discriminate these MRIs among testes with normal, mildly-injured, and severely-injured spermatogenic function with 83% accuracy. We believe that this system could be utilized for diagnosing male infertility in clinical practice.
